I was rather surprised to find her at my local Wal-Mart last night, but hey, why look a gift horse in the mouth. Vehicle mode- Thunderblast is a speedboat of some sort in this mode. There is a good amount of detailing on her. This is also a well armed boat. In adition to the large missile launcher gun she has two torpedos made of translucent orange plastic that peg onto holders on the side. A small machine gun is located near the front of the boat, and can pivot 60 degrees. Due to her being a shell former thier is no kibble whatshoever in this mode. This may just be me, but I think the boat looks like something that Cobra would build and use. I got the same vibe from Sideways jet mode. Transformation- This transformation is the perfect example of a shellformer. I kid you not. Unfold boat parts, unfold curled up robot. Robot mode-The down side is all the boat sides hanging off her back. So what is the upside? She looks fairly decent. They tried to make the boat parts look like wings, and she reminds me of the sweeps with that. The robot looks very femine, and she holds her gun fine. The shoulder joints are strong enough to hold it up. The only problem I have is that the arm will swing to the side from the wight. The cyber key gimmick transformes the missile launcher int a missile launcher that can fire the orange torpedos. In conclusion, I think whether or not you will want to get Thunderblast depends on how much you like Shellformer transformations. If you hate them, then skip her. If they don't bother you, then I recomment her.
